No solid news yet, the announcement is expected on the 5th of February as suggested by the "secret" message in the Cyberpunk 2077 trailer. Initial rumours mention the obvious PC version and some vague next-gen consoles. The dev team hiring is supposedly still ongoing so probably a release in the later parts of 2014.

The trailer message specifically mentions an open world setting which would presumably mean a departure from the large yet ultimately limited chapters as used in the previous games. So, Skyrim with a better climate and a more colourful palette?
